  • Work done by what

    Updated: 2012-08-31 21:49:46

  • Taking a Look into The Void

    Updated: 2012-08-27 06:00:05
    In 2007, physicist and author Frank Close compiled together a slender volume with an ambitious goal: to succinctly explain the scientific thinking behind the concept of "nothingness," the vacuum of non-existence, the very void in which nothing exists. The problem is that, simple as this concept seems at first glance, it gets incredibly complex very quickly in scientific terms, especially when you try to incorporate the findings of relativity and quantum physics....Read Full Post

And now you can learn about its history with some new beats and rhymes . Michael Wilson , AKA Coma Niddy , has been making science music videos for awhile now , and he sent me his latest dark matter rap this . weekend The rap hasn't reached Snoop Lion status yet , but it could become the next Large Hadron Rap created by former Physics Central team member Kate Mcalpine As far as I can tell , the science in the lyrics is quite accurate , and Niddy's ability to condense such a complex topic into a rap is commendable . The song's catchy to . boot You can watch the video below , and I've re-posted the science-y lyrics from Coma Niddy's Youtube page as . well

  • Risks and Rewards of arXiv Reporting

    Updated: 2012-08-13 21:17:00
    : skip to main skip to sidebar Monday , August 13, 2012 Risks and Rewards of arXiv Reporting Earlier today , some big names in the world of science journalism started a fascinating discussion on Twitter about reporting from the arXiv preprint server for physics papers . Because these papers usually have yet to be peer-reviewed or may never be peer-reviewed several questions naturally arose during the discussion . How can a journalist trust one of these papers What steps should reporters take to verify the claims in an arXiv paper , and should the process differ from reporting on a peer-reviewed article How much faith should reporters place in the peer-review process As a writer who frequently writes about papers from the arXiv , I've grown to appreciate this gold mine of often undiscovered
